一种用于质子交换膜燃料电池阳极催化剂及其合成方法数据集
收藏资源简介:
该数据集来源于质子交换膜燃料电池阳极催化剂的制备、表征过程产生的数据。本工作主要面向质子交换膜燃料电池(PEMFCs)阳极催化剂的研究,目的是寻找廉价高效的氢气氧化(HOR)催化剂替代当前昂贵的Pt基催化剂。通过对普通的Ru纳米颗粒进行表面改性,得到较高HOR反应活性的Ru/Ru(OxHy)催化剂。该专利中催化剂的形貌主要基于透射电子显微镜((TEM,JEOL JEM-1230))来进行观测,再根据X射线衍射(XRD,Rigaku D/Max 2500 VB2+ /PC)技术研究催化剂的晶体结构,同时利用X射线光电子能谱(XPS,Thermo Fisher ESCALAB 250Xi)技术分析催化剂表面元素价态,从而剖析催化剂的微观结构和组成。该专利中的电化学数据主要基于普林斯顿电化学工作站和群羿850e燃料电池测试系统产生,主要记录了催化剂在三电极电解池和两电极燃料电池单电池的电流、电压、阻抗和功率等物理量,然后再根据具体的实验数据进行分析和处理,从而得到催化剂的质量活性,峰值功率密度(PPD)以及稳定性数据等。本数据集数据量约90 MB。
This dataset is generated from the data collected during the preparation and characterization processes of anode catalysts for proton exchange membrane fuel cells (PEMFCs). This work focuses on the research of PEMFC anode catalysts, aiming to develop low-cost and highly efficient hydrogen oxidation reaction (HOR) catalysts to replace the currently expensive Pt-based catalysts. Conventional Ru nanoparticles were subjected to surface modification to obtain Ru/Ru(OxHy) catalysts with improved HOR reactivity. The morphology of the catalysts in this patent was primarily observed using transmission electron microscopy (TEM, JEOL JEM-1230). The crystal structure of the catalysts was studied via X-ray diffraction (XRD, Rigaku D/Max 2500 VB2+ /PC), while the surface element valence states of the catalysts were analyzed using X-ray photoelectron spectroscopy (XPS, Thermo Fisher ESCALAB 250Xi), thereby dissecting the microstructure and composition of the catalysts. The electrochemical data in this patent was mainly generated by the Princeton Electrochemical Workstation and the Qunyi 850e Fuel Cell Testing System. Physical parameters including current, voltage, impedance and power of the catalysts in three-electrode electrolytic cells and two-electrode single fuel cells were recorded, followed by analysis and processing based on the specific experimental data to obtain the mass activity, peak power density (PPD) and stability data of the catalysts. The total size of this dataset is approximately 90 MB.
